<p>
  Bootstrap包括两种类型的微调器。 默认的微调器类型称为<code translate="no" class="notranslate text-nowrap">border</code>（旋转的圆环边框），
  而可选的类型<code translate="no" class="notranslate text-nowrap">增长</code>（throbber样式指示器）。
</p>
<h3 id="border-spinner" class="bv-no-focus-ring"><span class="bd-content-title">边框 spinner<a class="anchorjs-link" href="#border-spinner" aria-labelledby="border-spinner"></a></span></h3>
<p>
  将默认<code translate="no" class="notranslate text-nowrap">边框</code>类型微调器用于轻型加载指示器。

<p>
  如果您不喜欢<code translate="no" class="notranslate text-nowrap">边框</code>spinner，
  请通过将属性类型设置为<code translate="no" class="notranslate text-nowrap">'增长'</code>来切换到<code translate="no" class="notranslate text-nowrap">增长</code> spinner。
  尽管从技术上讲它不是旋转的，但确实会反复增长！

<p>
  Spinners使用<code translate="no" class="notranslate text-nowrap">currentColor</code>作为其颜色，这意味着它继承了当前的字体颜色。
  您可以使用<code translate="no" class="notranslate text-nowrap">variant</code>属性使用标准文本颜色变体来自定义颜色，或在组件上放置类或样式以更改其颜色。
</p>
<p<code translate="no" class="notranslate text-nowrap">variant</code>属性将variant名称转换为Bootstrap v4类
<code translate="no" class="notranslate text-nowrap">.text-{variant}</code>，因此，如果您有自定义的文本颜色变体，请随时通过<code translate="no" class="notranslate text-nowrap">variant</code>属性使用它们。

  <strong>为什么不使用<code translate="no" class="notranslate text-nowrap">border-color</code>实体程序?</strong> 
  每个<code translate="no" class="notranslate text-nowrap">边框</code> spinner 至少为一侧指定<code translate="no" class="notranslate text-nowrap">透明</code> 边框，
  因此<code translate="no" class="notranslate text-nowrap">.border-{color}</code>实用程序将覆盖该边框。
</p>
<h2 id="size" class="bv-no-focus-ring"><span class="bd-content-title">大小<a class="anchorjs-link" href="#size" aria-labelledby="size"></a></span></h2>
<p>
  将属性设置为<code translate="no" class="notranslate text-nowrap">true</code>可以制作一个<code translate="no" class="notranslate text-nowrap">小</code>的微调器，可以在其他组件中快速使用该微调器。

<h2 id="alignment" class="bv-no-focus-ring"><span class="bd-content-title">对齐<a class="anchorjs-link" href="#alignment" aria-labelledby="alignment"></a></span></h2>
<p>
  Bootstrap中的Spinner使用<code translate="no" class="notranslate text-nowrap">rem</code>s, 
  <code translate="no" class="notranslate text-nowrap">currentColor</code>,和
  <code translate="no" class="notranslate text-nowrap">display: inline-flex</code>构建。 这意味着它们可以轻松地调整大小，重新着色并快速对齐。

<h3 id="margin" class="bv-no-focus-ring"><span class="bd-content-title">边距<a class="anchorjs-link" href="#margin" aria-labelledby="margin"></a></span></h3>

<p>
  通过<code translate="no" class="notranslate text-nowrap">标签</code>属性或<code translate="no" class="notranslate text-nowrap">标签</code>槽将隐藏的标签文本放置在spinner内，
  以供屏幕阅读器用户使用。 内容将放置在包裹在<code translate="no" class="notranslate text-nowrap">&lt;span&gt;</code>元素中的微调框内，
  该元素具有<code translate="no" class="notranslate text-nowrap">sr-only</code>类，</br>这将使标签可供屏幕阅读器用户使用。
</p>
<p>
  出于可访问性的目的，每个spinner在提供标签时将自动具有<code translate="no" class="notranslate text-nowrap">role="status"</code>属性。如果需要，
  您可以通过属性<code translate="no" class="notranslate text-nowrap">角色</code>轻松自定义<code translate="no" class="notranslate text-nowrap">角色</code>。
  如果未提供标签，则将不应用指定的角色。
</p>
<p>
  同样，当未提供标签时，spinner将自动具有属性<code translate="no" class="notranslate text-nowrap">aria-hidden="true"</code>，以向屏幕阅读器用户隐藏spinner。
